Celebrities go hard when it comes to Halloween [1], which is why we always turn to them when in need of costume ideas [2]. Hollywood's heavy hitters don't mess around when it comes to the most haunting day of the year (Heidi Klum [3], we're lookin at you) — and that doesn't just include their costumes. Every year, several stars show up with Halloween [4] makeup [5] looks that are, well, killer.
So if you're still stuck on what to wear for this Oct. 31, don't stress: The celebrity set has the inspiration you need, as per usual. While you may not have access to some of the prosthetics and airbrushing that these looks involve, you can still get some makeup motivation from these Halloween all-stars.
Jennifer Lopez and Casper Smart
Jennifer and her ex were dead sexy as a pair of skeletons at Heidi Klum [6]'s party in 2015. (RIP the relationship, too.)
Chanel Iman
The supermodel made the sexiest mummy we've ever laid eyes on at Heidi Klum [7]'s party in 2016. Speaking of eyes, her coloured contacts took this contoured look to the next level.
Emily Ratajkowski
OK, so it might just be yellow paint (or some other pigment) but this Marge Simpson look took all sorts of commitment. Judging by the genius results, it was 100% worth it.
Rihanna
In 2014 the singer and mogul was a hero in a half shell, along with two pals. The Ninja Turtles never looked so hot.
Heidi Klum
She's got a reputation to live up to as the unofficial queen of Halloween [8] and in 2017 she upped the ante as the werewolf from Michael Jackson [9]'s "Thriller" music video. Well played, Miss Klum.
Alessandra Ambrosio
The model Alessandra Ambrosio looked other-worldly as a unicorn for Halloween [10] 2017. From the glitter to the bright blue contacts, she nailed this look well, on the head.
Lisa Rinna
In 2010 everyone's favourite Beverly Hills housewife dressed up as the original housewife, Lucy Ricardo from I Love Lucy. Check out those eyebrows!
Michelle Trachtenberg
The Gossip Girl [11] star is known to take her Halloween [12] makeup looks pretty seriously. In 2011 she went all blue and Tim Burton-esque for the big night.

Trachtenberg went botanical at the Just Jared party in 2016.
Michelle Trachtenberg
She got all dolled up — and broken — in 2014.
Sara Sampaio
The Portuguese beauty was bloodied up for the holiday in 2014.
Josephine Skriver
Skriver was a dead ringer (sorry) for a skeleton in 2015 at the Just Jared party.
Ashanti
Blue paint, a wig, and a hat transformed the singer into Smurfette in 2015.
Nicole Scherzinger
We're not exactly sure what she was meant to be but Scherzinger's beauty look was gorgeous and on point at Heidi Klum [13]'s party in 2015.
Nicole Scherzinger
She made a captivating Cleopatra, complete with dramatic eyes, in 2017.
Katy Perry
"I'm with her?" Or "I AM her?" Katy got all done up as Hillary Clinton, along with her very own Bill, in 2016.
Sarah Michelle Gellar
She wasn't sure if she was a mermaid, a unicorn, or a showgirl, but Sarah's 2017 makeup look for the GOOD + Foundation Halloween [14] Bash didn't need any additional costuming. From the sequins to the coloured hair extensions to the lashes, she didn't disappoint.
Jay Manuel
Mr. Jay essentially gave a master class in contouring when he showed up in this look for Heidi Klum [15]'s 18th annual Halloween [16] party. Bonus points for the eerie coloured contacts.
Zac Posen
The designer opted for a seriously amazing zombie look for Heidi Klum [17]'s annual party. (You could say he knocked 'em dead.)
Gus Kenworthy
The Olympic skier went as Dooneese From Saturday Night Live [18] in 2017.
